There are about 1,426 billionaires in the world this year.
They are the wealthiest of the wealthy. But only 29 members of this elite list
are under 40 years old, with that exciting combination of money and youth.

Those 29 have a total of $119 billion between them. Ten come
from the technology sector, including four from social networking giant
Facebook. Eleven come from the United States, the rest from countries abroad. While
Five are newcomers to the billionaire ranks.

No. 1: Dustin Moskovitz

Age: 28

Net Worth: $3.8 billion

Moskovitz, Mark Zuckerberg‘s former roommate,
no longer works at Facebook, the social networking giant that he co-founded. A
signee of Bill Gates‘ and Warren Buffett’s Giving Pledge, Moskovitz bikes to
work, flies commercial, and pitches his own tent at Burning Man.

No. 2: Mark Zuckerberg

Age: 28

Net Worth: $13.3
billion

Few CEOs of any age
are under more media scrutiny than Zuckerberg (who’s only 8 days older than
Moskovitz). Since taking Facebook public in May 2012, and getting married days
later, the hoodie-wearing founder has seen his net worth rise and fall with
every fluctuation of the stock price.

Researchers from Washington University
School of Medicine in St. Louis have shown that nanoparticles infused with a
toxic bee venom can kill HIV. The researchers hope to take this new compound
and develop a vaginal gel that can prevent the further spread of the disease.

The key to this discovery, which was made
by Samuel A. Wickline and his team at Washington University, involves cytolyic
melittin peptides. Melittin is found in bee venom, and it has the fortuitous
trait of being able to degrade the protective envelope that surrounds HIV.

For the experiment, Wickline’s team
prepared free melittin and melittin-loaded nanoparticles and set them against
various strains of HIV (CXCR4 and CCR5 in particular). The researchers then
showed that melittin, when delivered in these large and free accumulations, can
make life miserable for
